Pathfinding (WIP): Use MarkBu's pathfinder mod as the new pathfinder.

Actions: Modify walk_to_pos to use new pathfinding code.
Allow support for giving positions as strings or tables referring to specific places on Places Map.
Spawner: Assign beds to NPCs.
Increase amount of NPCs now being spawned as they are able to reach top floor beds.
Places: Slight overhaul and changes. Add more info to places.
NPC: Hide nametag.
